While running process with gdb following back trace was obtain:

What happens when you do a tar tvf file first? It should tell you where it wants to write to. First you need to very that it can in fact write to the path inside the tar file with regards to permissions and disk space...

Yes i have verified with -t option, permissions and disk space seems to be fine

What do you mean -t option? What's with the minus???

Please post the exact command you are issuing.
Please post unix/Linux version.
Are you running this command as root? Or a standard user?

Command:
Code:
tar -tvf NCSanJose1_req_rep.tar

Linux version: Linux netstorm-X9DRW 3.8.0

I was running this command as standard user

A few more questions I'm afraid.:-
  • What output do you get? Just the last few lines if it's very long.
  • Are you running this on the command line or batched up with the output being collected?
The second point is that tar may only write to a log file every time it fills a block of output, frequently 1024 bytes but not necessarily. This can lead to partial output whilst a restore is still running. On a terminal it should keep going though.

Commands:
Code:
tar -xf NCSanJose1_req_rep.tar

This command was running as part of shell script, which stuck

In order to check tar file with verbose option, command was ran on console which exited successfully.
Code:
tar -tvf NCSanJose1_req_rep.tar
